Since its introduction in China, BIM has experienced ups and downs but has shown explosive growth in recent years. Policies promoting BIM have been steadily implemented at both central and local levels, accelerating its development and adoption within the domestic construction industry. Today, I will discuss what changes BIM application will bring to architectural design in China.
1. The Essence of Architectural Design Remains Unchanged
Architectural design, rooted in aesthetics and artistry, cannot be fully replicated by computers. BIM primarily influences the technical aspects of design rather than the conceptual process. BIM modeling tools are not intended for conceptual design; architects will continue to lead the conceptual process and preserve the core essence of design. During the BIM application in architectural design, BIM assists architects in achieving results that were difficult with traditional 2D methods, but it does not fundamentally alter the artistic or aesthetic nature of architectural design.
2. Changes in Architectural Design and Tools for Design Implementation and Refinement
The conceptual design phase translates abstract ideas into concrete expressions. The tools used must synchronize closely with the architect’s thought process—even a traditional pencil meets the needs of this phase. In contrast, the design refinement phase demands precision in positioning, accurate measurements, correct proportions, and clear graphical representation. These phases require different tools, and using them incorrectly or in reverse order can negatively impact both design quality and efficiency.
3. Architectural Design Is No Longer a Solo Effort
Historically, architects managed the entire architectural design process, delegating specialized tasks to technical experts and then integrating the results. In the BIM era, however, multidisciplinary collaboration replaces the traditional solo performance of architects.
4. BIM Is a Collaborative Effort Involving Multiple Stakeholders
Traditional architectural projects often involved negotiations and compromises between the owner and architect, with results falling short of either party’s ideal. BIM facilitates collaboration among owners, BIM managers, architects, engineers, construction teams, and suppliers. Compromises are embedded in design parameter selections, enabling outcomes that closely align with the goals of all parties involved.
5. 3D Models Will Replace 2D Drawings as the Primary Design Medium
Unlike the hundreds or thousands of isolated 2D CAD drawings used previously, a single 3D model can now serve as the primary medium for communicating design intent. Even 3D models without embedded architectural data offer substantial advantages over traditional 2D graphics. As a result, 2D drawings will gradually become supporting tools used for preliminary or auxiliary work rather than the main form of design expression. In the future, design deliverables will predominantly come directly from views embedded within 3D models.
6. Advances in Non-Euclidean Geometry and Nonlinear Science Have Liberated Design Thinking and Accelerated BIM Adoption
By leveraging 3D computer technology, designers can now create models based on complex forms such as folds, solids, droplets, organic textures, waves, peaks, and even topological structures like Möbius strips and Klein bottles. These shapes inspire architects and expand creative possibilities beyond classical architectural principles, as seen in projects like the Kazakh National Library designed by BIG. This liberation of design thinking and enhanced use of geometric information embedded in 3D models have significantly accelerated BIM adoption.
7. BIM Results from Collaboration Among Multiple Software Applications, Not a Single Tool
Beyond BIM modeling software, successful BIM implementation requires integration with other tools related to building performance simulation, visual rendering, and project management. In the BIM era, no single software dominates; architects must learn and use multiple interoperable tools. Continuous updates to both software and hardware are essential, making it impractical to rely on outdated computers. Consequently, architects face increased investments in technology and skilled personnel.
8. BIM Is Not Just a Supercharged Drawing Tool, and Its Purpose Extends Beyond Producing Construction Drawings
BIM models carry comprehensive information covering the entire building lifecycle. Architectural designers must recognize that the goal of design is more than generating construction drawings. BIM models serve long-term functions, supporting building maintenance and future updates, replacing today’s scattered paper blueprints.
In summary, BIM is set to become a dominant trend in China’s architectural design landscape. However, challenges and obstacles in BIM implementation remain significant. Recognizing these difficulties is essential for advancing BIM development. That concludes our discussion on what changes BIM application will bring to China’s architectural design.
